Problem with acquisition data.

[Brasantos]

Using a board PCI MIO 16E�1, coupling with chassis 1000 plus module SCXI 1125, for the acquisition data of the floating signal (transducer), I hope to visualize the waveform of the analog input using the MAX test panel, but this is outside of my expectancy. What�s happening?

Greetings,

You have two primary methods of reading data from MAX. You can set up a Virtual Channel and open a Virtual Channel Test Panel by righ-clicking on your new Virtual Channel and choosing Test. For information regarding the creation of a Virtual Channel you may reference the following Knowledge Base entry.

What Is a Virtual Channel? How Do I Create One?http://digital.ni.com/public.nsf/websearch/31C55E253B023189862569850068B8AE?OpenDocument

You can also open MAX and choose Help -> Help Topics -> NI-DAQ from the menu and read about how to create a virtual channel.

You also have the option of using your DAQ card test panel and typing in a channel string which corresponds to a channel on your SCXI module. The following Knowledge Base discusse
s channel strings. The article is not specific to LabVIEW.

Valid SCXI Channel String Arrays under LabVIEW

You simply enter the string into the channel field of your DAQ card's test panel. For instance if your SCXI chassis is chassis 1, your 1125 module is in slot 1 and you are reading from channel 2 then your string would look like "ob0!sc1!md1!2"

These articles should definitely put you on the right path.
